在数组中搜索匹配的属性 [英] Search an array for matching attribute

问题描述

我有一个数组，我需要返回一个餐馆的名字，但我只知道它的食物属性的值（不是它的索引号）。

I have an array, I need to return a restaurant's name, but I only know the value of its "food" attribute (not it's index number).

例如，如果我只知道鸡肉，我怎么能返回肯德基？

For example, how could I return "KFC" if I only knew "chicken"?

restaurants = 
  [
    {"restaurant" : { "name" : "McDonald's", "food" : "burger" }},
    {"restaurant" : { "name" : "KFC",        "food" : "chicken" }},
    {"restaurant" : { "name" : "Pizza Hut",  "food" : "pizza" }}
  ];

推荐答案

for(var i = 0; i < restaurants.length; i++)
{
  if(restaurants[i].restaurant.food == 'chicken')
  {
    return restaurants[i].restaurant.name;
  }
}
